# How the form builder works

> A tour of the builder — the Build, AI, and Logic tabs, the live preview, and publishing your changes.

The builder splits in two: a live preview of your form on the left, your field list on the right. Three tabs across the top — **Build**, **AI**, and **Logic** — switch what the right side does. Nothing you change reaches your live form until you select **Publish**.

## Open the builder

1. On **Home**, select your form's name.
2. Select **Edit** in the top-right corner.

## The three tabs

- **Build** — the default. Every field you've added is listed on the right, with **Add field** at the bottom. The preview on the left updates as you type.
- **AI** — swaps the field list for a chat panel: *Ask me to change your form*. Describe a change in your own words — "Add a phone number field", "Make it shorter" — or use **Attach** to hand it a document.
- **Logic** — rules that show or hide fields based on what people answer. See [Show or hide fields with conditional logic](/building-forms/conditional-logic).

## Two ways to edit a field

Select a field's name in the list to rename it in place. For everything else, select **Advanced edit** on that row — the **Edit field** dialog has a **General** tab (label, field type, placeholder, help text, and the type's own settings) and a **Validation** tab (**Required Field**, **Unique Values Only**, and any limits the type supports).

Each row also carries **Drag to reorder**, **Duplicate field**, and **Delete field**; hovering between two rows reveals **Insert field here**.

Deleting a field people have already answered asks you to confirm, and tells you how many responses it has: *After you publish, it won't appear on the form. Existing responses keep their answers.*

## The buttons beside the tabs

- **Settings** opens the form's **Settings** tab.
- **Version history** lists the versions you've published.
- **Copy link** copies the form's public URL.
- **Open form** opens the live form in a new tab.

## Publish, or throw the changes away

A form that has never been published shows a reminder — *Your form stays private until you publish* — and a single **Publish** button.

Once it's live, editing anything replaces that with two buttons: **Publish changes** pushes your edits out, **Discard** throws them away and returns the builder to the last published version. Respondents keep seeing the published form until you publish again.

Discarding asks you to confirm first — *Discard your unpublished draft changes? This cannot be undone.*

## Everything else about your form

Select your form's name in the breadcrumb to leave the builder. That page holds the rest of the form's tabs: **Insights**, **Submissions**, **Integrate**, **Share**, and **Settings**.
